Mother Teresa was born in Yugoslavia, on August 27th, 1910. She attended the government school near her home until she was eighteen. At that time, some doctors and nurses from Yugoslavia were working in India, and they often wrote to the school about their work. She decided to join them one day.

When she finished school, she went first to Britain. Then a year later she went to India, where she began to train to be a teacher. After training, she was sent to Calcutta, where she taught geography at a school and soon after became headmistress(女校长).

However, although she loved teaching, in 1946 Mother Teresa left the school and went to work in the poor parts of Calcutta. Later she trained to be a nurse in Panta, and then began her work helping the poor and comforting the dying in the streets of the city. Slowly, others came to help her, and her work spread to other parts of India.

Mother Teresa is now a well-known person. Many photos have been taken of her, as she travels the world to open new schools and hospitals in poor countries. In 1979, she was given the Nobel Peace Prize for the lifetime of love and service she has given to the poor.
